Question

Besides hearing, which is an additional sensory role of the ear?

Answers

  1. Taste
    • Rationale:

      The mouth and the specialized chemoreceptors that are found here are responsible for taste, not hearing. The mouth does not play a role in equilibrium.

  2. Smell
    • Rationale:

      The nose along with the specialized chemoreceptors that are found here are responsible for smell, not hearing. The nose does not play a role in equilibrium.

  3. Equilibrium
    • Rationale:

      The ears are responsible for the special senses of equilibrium and hearing. Equilibrium is defined as a state of balance between opposing forces or actions that is either dynamic or static.

  4. Homeostasis
    • Rationale:

      The ears do not play a direct role in homeostasis. Homeostasis is the body’s ability to maintain stable internal conditions in spite of continually changing conditions outside of the body.

Overview

There are five special senses within the body. The ear is responsible for two of these special senses.

Explanation

Learning Outcomes

The five special senses of the body include equilibrium, hearing, smell, taste, and vision. The ears are responsible for two of the five special senses. In addition to hearing, the ears also play a role in equilibrium.

Test Taking Tip

Consider any secondary roles for each of the senses when determining the correct choice for this question.
